The system adopts a five level fire protection strategy for comprehensive safety. The first level activates automatic shutdown and power isolation at the earliest sign of danger, cutting energy supply to stop escalation. The second level deploys perfluoroketone clean agent gas, which quickly suppresses fire sources without leaving residue or damaging equipment. If further protection is required, the third level engages a water spray system to cool down battery packs and prevent potential reignition. This multi layer approach provides a complete safeguard, ensuring reliable operation in the most critical moments.
